I wrote code for the development chip 8021 to
test the A/D. I never got one to actually give
me a true 8 bits. 6 to 7 someplace was typical.
I made a little fixture to plug it into as well.
The developement chip was in one of those funny
packages, like the 432's.
For those that haven't seen that package, there are
some photos on my site:

Recently I was reading an old Intel Development Systems
data book, and noticed the 8021 emulator board using
the ceramic leadless QUIP package. I think Intel used
that for other bond-out chips as well, back in the early
1980s; by 1985 they had moved to the JEDEC type A (or was
it B?) square 68-contact ceramic leadless chip carrier (CLCC).
As far as I know, the only Intel chips packaged in the
ceramic QUIP which were offered for sale were the 432
components. And I'm not aware of any other vendor using
the ceramic QUIP.
In the 1980s Motorola and HP used a different square ceramic
leadless chip carrier, called a SLAM package. I'm not sure
what that stands for. The only common part to use it was
the Motorola DSP56001. Somewhere I still have a handful of
those and the sockets for them. Maybe I should sell them for
big bucks to a chip collector. :-)
